Checked all relevant fuses? Possible fan speed controller (hedgehog ) problem ? 

This morning I tried to check the fuses but seem to be ok, its means there is something else, of which not sure of

14 & 33.
What are the actual symptoms.
Does the climate panel illuminate.
Have you control over all fan speeds.
Does the fan stop when climate panel switched off.
Have you tried a manual re-set (OFF & AUTO held in together.
Can you hear the vac flaps resynching.
If fan speed is controllable have you tried removing vac pipe from top of HBV to see if you get heat.

Hello Sir, 1. there is weak cold air coming through the vents; 2. I've tried the "OFF & AUTO" reset but nothing happens, no any sound; 3. the climate panel seem to be working ok as it shows when switched on; 4. Checked the fuses, all seem to be ok. 5. Seat heating is working properly. Thus all I can note at the moment. Thanks very much for your help.

Hello sir, the real symptoms are:
*the air from the vents is cold and very weak that seems the blower could not be working properly;
*the car forms mist and ice inside the windscreen;
*I can control everything on the climate control panel without any problem.
*Yes the fan stops when switched off.
*the seat heating is working properly
*I haven't tried to remove the vac pipe from top because I'm not sure what it is, could you please help to gives some simple instruction so that I could try that.
Thanks very much sir

Ive been trying to find a pic of a 2.2 HBV but no luck so far. I wonder if someone on OOF might have one ?

Same place as the inferior V6

[albitz]

No Pic ? ! SHOCKING !!

Gibby here is the guide for changing the HBV on the V6 engine.The 2.2 is similar I think.Its right at the back of the engine and wiull be awkward.The bottom picture shows the small vacuum pipe on top of the valve which you need to pull off to see if you then get any heat in the car.If you do (or dont) get heat in the car after youve taken it off,post your results here and Im sure more advice will be offered.

If resistor is donald, fans will run on unless fuse #33 is pulled

Not always. Sometimes the failure mode is where it will not provide any power to the fan motor.  In fact, IME, this seems to be the most common failure mode. Only seen the constant running if its been soaked by the scuttle drain.

As it seems the fan is non functional (I assume you have tried manually turning the fan right up ), I would suggest removing the glovebox, disconnect (and insulate!) the wires from speed controller, and apply a 12v fused feed to the fan directly, to see if it spins. If it does, I'd be suspicious of the speed controller (hedgehog).

Also, has your scuttle drain blocked, as that can kill the speed controllers, as they don't like water.

As to no hot air either, check first that the pipes going to the bulkhead are hot. There could be a vac problem causing no heat. Easy test if its a vac problem is pull the vac hose off the top of the HBV.

Good afternoon sir, I have seen the link you posted and it looks fine, its really well detailed and very exciting to read through. Now its hands on work. Thanks very much, your are a man of good heart and very rare to get hold of these days, May the Dear Lord bless you. After fiddling around I will post the outcome.

Happy to try to help with what little knowledge I have Gibby. Im not available to come and help you just at the minute,due to a family medical emergency.Hopefully that will all be ok in a few days,but Im not certain at the moment.

Hi sir, so does this HBV usually need replacement or there is something to do for it to function properly? And if it needs to be replaced where could it be bought? Thanks, I wish you good health.
